Going off at a tangent and after 6am…I looked south of Chiswick around 6:47am yesterday (Weds) and was slightly astonished to see in the far distance what looked like four Heathrow flights flying in formation. Obviously a bit of an optical illusion and I guess not that uncommon if you stood staring at the sky holding patterns for long enough - but it really caught my attention.
I called back the info on WebTrak today - not having had a camera with long lens to hand at the time. They were - anti-clockwise from the left:
1. BA176 JFK to Heathrow at 12,900ft. 2. AA106 JFK to Heathrow at 7,900ft. 3. AA056 Miami to Heathrow at 9,600ft. 4. VS012 Boston to Heathrow at 7,000ft.
